HD – DBT/DBWT – Pressure Relief Valve
Gain absolute command over your heavy machinery from a safe distance with the HD DBT and DBWT Series Remote Control Pressure Relief Valves. Available through THM Hydraulics, these highly specialized valves are engineered to regulate the pilot pressure of larger, main-stage relief valves from a remote operator station or centralized control panel. Designed specifically for low-volume pilot flow (up to 3 L/min) while comfortably managing intense system pressures up to 315 bar, this series allows operators to safely and instantly adjust hydraulic forces without needing to physically approach the high-pressure power unit. With versatile adjustment elements and standard sub-plate mounting, the DBT/DBWT series bridges the gap between operator safety and precise fluid power control.
Core Technical Specifications:-
- Component Architecture: Remote Control Pilot Pressure Relief Valve
- Model Type: HD-DBT (Standard Remote) and HD-DBWT (Solenoid Actuated Remote)
- Maximum Operating Pressure: Up to 315 bar
- Maximum Flow Capacity: Up to 3 L/min (Optimized for pilot flow)
- Control Range: Long-distance remote control capability
- Pressure Adjustment: 3 distinct optional adjustment elements
- Mounting Style: Sub-plate mounting
Key Features & Engineering Advantages:-
- Long-Distance Remote Operation: By piping this small valve to the pilot port of a main relief valve, operators can dial in exact system pressures from a remote control room, cabin, or operating panel located far away from the dangerous, high-pressure equipment.
- DBT vs. DBWT Configurations: The DBT offers highly accurate mechanical remote adjustment, while the DBWT integrates solenoid actuation, allowing for electrical unloading or rapid switching of the remote pilot pressure via your PLC or control switches.
- Optimized Pilot Flow: The 3 L/min flow limit is perfectly calibrated to manage the delicate internal pilot circuits of massive hydraulic valves without wasting main pump energy or generating excess heat.
- 3 Custom Adjustment Elements: Tailor the operator interface to your security needs. Choose from different adjustment mechanisms to allow easy tuning while preventing unauthorized personnel from tampering with critical machine limits.
- Leak-Free Panel Integration: Designed exclusively for sub-plate mounting, ensuring a clean, robust, and highly organized installation directly onto operator control consoles or auxiliary manifold blocks.
Ideal Industry Applications:-
The long-distance control and compact footprint make the HD DBT/DBWT Series the premier choice for:
- Centralized Control Rooms: Allowing operators to adjust the hydraulic pressure of massive industrial presses, rolling mills, and forging equipment from safely behind blast-shields or in elevated cabins.
- Marine & Offshore Winches: Providing precise tension control for heavy deck machinery directly from the ship's bridge or remote operating stations.
- Mobile & Construction Equipment: Mounting directly inside the enclosed cabins of heavy excavators and cranes, giving the driver instant, fingertip control over auxiliary hydraulic pressures.
- Hydraulic Test Benches: Enabling test engineers to safely dial up pressures on prototype cylinders or motors from behind a protective safety barrier.
Why Choose the HD DBT/DBWT Series?
- Maximize Operator Safety: Keep your workforce away from high-pressure lines and noisy power units. This valve brings the control exactly where the operator needs it.
- Instant System Tuning: Eliminate the downtime of shutting off the machine, walking to the power unit, making an adjustment, and walking back. Tune your system dynamically as the job requires.
- Clean & Professional Consoles: The sub-plate mounting allows you to build clean, ergonomic control panels without a mess of hard-piped lines crowding the operator's workspace.
